BLUE SCREENS

Hi to everyone at What the Tech & a very Happy New Year to you all. My name is Malcolm & I am still very much in the learning mode with my PC . I would therefore ask whoever draws the short straw to bare this in mind.
For a number of months now I keep getting a BLUE SCREEN & despite the help from a knowledgeable friend & an expert they seem to be getting more frequent. There is no set pattern as to when they happen. It has shown up when switching on, surfing the net , running spy & anti virus programs etc. etc. I dont believe that they are the result of new soft or hardware. I understand that it could be very difficult to solve this problem but I would be very gratefull of any input you can put in. I can give you the last seven STOP messages if you require them. Please note that all these messages are different.
Regards
Malcolm.

Sorry to hear of the blue screen problems you have been experiencing. Yes it would be helpful for you to let us the error codes
(from the blue screens), as this may give us something to go on.

You mention that don't believe that new software or hardware is implicated, but it would also be helpful to know what system changes or new or uninstalled applications have been carried out over the time since the problem began.

the fact that you are getting a lot of these blue screens is not good................. there is obviously a problem with your installation causing the instability and as you say it may not be easy to find a solution.

If you go here:http://pcpitstop.com/
and look under tests and scans in the left hand panel you can perform a "full test" This is free and will provide lots of important information about your machine and what is going on inside it. If you include the "Tech Express" link in your next reply to us here it will help us to point you in the right direction.

You will be asked to register at PcPitstop and accept an ActiveX control, both are generally considered safe from that site.

Your System Score
Overall score for system "DAYS": 1845
Discuss your score in our online forums!
Your system score is merely a rough estimate of your computer's performance. We recommend that you use your score as a way to track your own computer's performance and health over time, not as a way to compare your PC to other PCs. If you would like to see where your computer stands in the population of systems tested at PC Pitstop, click here for a comparison. Remember: the important thing isn't the actual numerical score, but the performance and security of your system.
How the score is calculated
The overall system score is made up of the weighted sum of your performance scores in the areas that PC Pitstop tests. Internet performance is capped at 100 points; connections faster than 1000Kb/sec will receive the maximum possible score of 100 for that category. A deduction is made for any red-flag or yellow-flag tips that you receive.
"What is the highest possible score?"
Our score is an open-ended scale. As long as they keep making faster computers there will be higher scores. On the System Comparisons page, we show the typical scores for systems that are similar to yours.
"How do I get a higher score?"
You can usually increase your score by clicking on each tip and following the instructions you receive so that you can eliminate the problem. Then try to eliminate as many background programs as possible since they can interfere with CPU, memory, and disk performance; you can see a color-coded list of what you were running during the test on the Test Details page. You may be able to get better scores by finding faster video drivers. Finally, you can improve the performance of the system by upgrading or replacing components.

Hi MALC
I'll cut directly to the "cheese".
IRQL_NOT_LESS_OR_EQUAL : This error occurs only when you have either a buggy driver or an actual hardware conflict.
Solve the problem by re-install all drivers for your hardware with the driver.installation cd which came with your pc. Check your hardware for conflicts. To check for conflicts, follow these steps:
1: Go to the control panel, either through the start menu or in "my computer"
2: Find the icon System
3: Go to the hardware tab
4: Click devices (dont know what its called in english, have a danish version, sry)
5: Look for yellow ? or !. ? means missing driver, and ! means there is a hardware conflict.
If you have a missing driver on any hardware, update its driver with your afore mentioned cd or let windows try find one on the net.
Concerning a hardware conflict I must be honest, and tell you that I don't know how to solve that. Maybe someone else in this great forum can tell you
BAD_POOL_HEADER : Is a tricky one. It only occurs when you have made some critical change to your system which doesn't comply with your hardware or system setup. To locate the culprit here, really depends on you remembering which changes you have made to either or both.
All the error messages containing STOP...etc. is your systems critical stop function. It automatically stops before any more harm can occur, which brings us back to IRQL_NOT_LESS_OR_EQUAL.
Hope this post helps you somewhat further to solve your problem.
Kind regards Abydos
